NINJA Checkout Fields gives shop managers a clean admin screen ( under WooCommerce Checkout Fields) where they can: * **Enable or disable** any standard checkout field (Billing, Shipping, Additional/ Order). * **Mark fields as required or optional** — override WooCommerce’s defaults to fit your workflow. * **Rename the label** shown to the customer, without editing template files or child themes. * **Set a placeholder** (hint text inside the input) per field. * **Reorder fields** with simple priority numbers or ▲/▼ buttons — lower priority = earlier on the form. * **Live preview** that shows the derived checkout layout — exactly what your customers will see — updating as you edit. Everything is saved in a single WordPress option. No database tables, no rewrite rules, and no external requests for managing your checkout (the only opt-in exception is the “NINJA Updates” email subscription described below). Activate, configure, done. **Protected fields:** `billing_country` and `billing_email` can never be disabled because WooCommerce requires them to complete order processing. The plugin enforces this server-side regardless of what the admin UI sends. **Reset:** One click restores the full WooCommerce default field set. ### WooCommerce integration NINJA Checkout Fields declares HPOS (High-Performance Order Storage / Custom Order Tables) compatibility and uses the standard `woocommerce_checkout_fields` filter so it’s compatible with any WooCommerce version that exposes that filter (8.0+). It does not modify database tables, templates, or core files. ### Stay updated (optional) The admin screen has an optional “NINJA Updates” card: tick the consent box and enter your email to hear about plugin updates and new NINJA modules. It is entirely opt-in — nothing is sent unless you submit that form — and you can unsubscribe at any time with one click. This is the only feature that ever contacts an external service. ## Screenshots * [[ * Field manager — at-a-glance KPI cards plus per-field controls (Enabled, Required, Label, Placeholder, Priority) for the Billing, Shipping, and Additional sections. * [[ * Live preview — the derived checkout field list in priority order, exactly what customers will see, with one-click Save and Reset to WooCommerce Defaults. ## Installation 1. Go to **Plugins Add New**, search for “NINJA Checkout Fields”, and click **Install Now** — or upload the ZIP under **Add New Upload Plugin**. 2. Click **Activate**. 3. Open **WooCommerce Checkout Fields** in the admin menu. 4. Enable, disable, relabel, reorder, and set placeholders as needed. 5. Click **Save Changes**. Your checkout updates immediately. WooCommerce must be installed and active. If it is not, the plugin shows an admin notice and does nothing else. ## FAQ ### Can I disable the billing email or country? No — and that’s deliberate. WooCommerce cannot process an order without those two fields. The plugin protects them server-side; the UI makes it clear they’re required. ### Will this break my existing orders or customer data? No. The plugin only affects the checkout form presented to new customers. Existing orders are untouched. Overrides are stored as a single WordPress option, so you can reset at any time. ### Does it work with HPOS (High-Performance Order Storage)? Yes. HPOS compatibility is declared and the plugin does not read order data at all. ### Does it make any external requests? Not unless you ask it to. All checkout-field management runs entirely inside your WordPress install. The single exception is the optional “NINJA Updates” card: only if you tick its consent box and submit your email does the plugin contact ninja. si to register your subscription. Leave it alone and nothing is ever sent. ### What happens if I deactivate the plugin? The `woocommerce_checkout_fields` filter is no longer applied, so the default WooCommerce fields come back immediately. Your saved configuration is preserved and restored when you reactivate. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “NINJA Checkout Fields” is open source software.
